GPU Role

The NVIDIA GeForce RTX 3080 Ti is the undisputed driver of this system’s Doom performance. Built on the Ampere architecture with the GA102 chip, it packs 10240 shading units, 320 texture mapping units, and 112 ROPs. The card’s 12 GB of GDDR6X memory, with a 384-bit bus delivering 912.4 GB/s of bandwidth, ensures that even the game’s high-resolution texture assets are fed without stutter. The base clock of 1365 MHz and boost clock of 1665 MHz provide the computational foundation, while the FP32 throughput of 34.10 TFLOPS gives the card substantial headroom for the game’s Vulkan renderer.

The measured FPS data underscores the GPU’s dominance. At 4K Ultra, the average of 66 FPS is a demanding load, yet the card still manages playable frame rates. The jump from 4K Ultra to 4K High (81 FPS) represents a 22.7% increase, suggesting that the Ultra preset includes settings that heavily tax the GPU’s shader and ROP units. The 4K Low result of 109 FPS indicates that when the GPU is less burdened, the engine can run at high refresh rates even at the highest resolution. The RTX 3080 Ti’s 80 RT cores and 320 tensor cores are present in the silicon, but Doom (2016) does not leverage ray tracing or DLSS, so these units remain largely idle; the game’s performance is purely a function of raw rasterization power and memory bandwidth.

Resolution Scaling

The frame rate scaling from 1080p to 4K follows a classic GPU-bound curve, but with a notable flattening at the lower end. At Ultra settings, the average FPS drops from 188 at 1920x1080 to 122 at 2560x1440 (a 35.1% reduction) and then to 66 at 3840x2160 (a further 45.9% reduction from 1440p). This steep decline at 4K is characteristic of a GPU-heavy workload, where the pixel count quadrupling from 1080p to 4K overwhelms the ROPs and memory bandwidth.

The pattern changes at Low settings. Here, the 1080p average of 278 FPS drops to 202 at 1440p (27.3% reduction) and then to 109 at 4K (46.0% reduction from 1440p). The 1080p Low figure of 278 FPS is notably close to the 1440p Low figure of 202 FPS, suggesting that at 1080p Low, the CPU is beginning to limit performance. The Ryzen 7 3700X, with its 8 cores and 16 threads at a boost clock of 4.40 GHz, cannot feed the RTX 3080 Ti fast enough to reach 300+ FPS. This is further corroborated by the 1080p Medium result of 265 FPS, which is only 13 FPS lower than Low, indicating that the CPU is the bottleneck even at Medium settings. The 1440p Medium result of 176 FPS shows a more balanced scenario, while 4K Medium at 95 FPS is firmly GPU-limited.

Settings Recommendations

For the best experience, the data points to High settings as the optimal balance. At 4K, High delivers 81 FPS, which is 22.7% faster than Ultra (66 FPS) and only 14.8% slower than Medium (95 FPS). The visual uplift from Medium to High is typically significant in Doom, while the drop from High to Ultra often involves diminishing returns. At 1440p, High produces 149 FPS, which is 22.1% faster than Ultra (122 FPS) and 15.3% slower than Medium (176 FPS). This pattern holds at 1080p, where High achieves 230 FPS versus Ultra’s 188 FPS.

The Medium preset is also a strong candidate for competitive play. At 1080p, Medium yields 265 FPS with a recorded min FPS of 225, ensuring buttery smoothness on high-refresh monitors. However, the 1080p Low result of 278 FPS suggests that dropping to Low provides only a marginal gain of 13 FPS over Medium, making Low a poor choice for the trade-off in visual quality. Ultra is best reserved for 1440p, where 122 FPS remains above the 60 FPS threshold, or for 1080p, where 188 FPS is still excellent. The 4K Ultra result of 66 FPS is playable but leaves no headroom for demanding scenes, so High is the safer choice at that resolution.

How This Combo Ranks

Among the 3712 hardware combinations tested in Doom, the AMD Ryzen 7 3700X + NVIDIA GeForce RTX 3080 Ti configuration holds the 1023rd position. This places it in the 72nd percentile of all tested systems, meaning it outperforms roughly 72% of other combos. The ranking reflects the RTX 3080 Ti’s high-end rasterization capability, though the Ryzen 7 3700X, while a capable 8-core processor, is not the fastest CPU available for this title. The gap between this combo and the top-end configurations likely stems from CPUs with higher single-thread performance, which would push the 1080p frame rates even higher.

The nearest synthetic rivals for the CPU—the AMD Ryzen AI 7 350 (0.1% ahead), AMD EPYC 4244P (0.1% ahead), and Intel Core i5-13450HX (0.2% behind)—are all within a 0.5% margin, indicating that the Ryzen 7 3700X is competitive with modern mid-range processors in overall compute. The GPU’s nearest rivals—the AMD Radeon Pro 5300 (0.8% ahead) and NVIDIA GeForce RTX 5070 (2% ahead)—are also close, but the RTX 3080 Ti’s raw power in a game like Doom likely boosts the combo above those with weaker GPUs.

Measured FPS Breakdown

At 1920x1080, the system achieves its highest frame rates. Low settings produce an average of 278 FPS. Medium settings average 265 FPS, with a min of 225 FPS and a max of 305 FPS. High settings average 230 FPS. Ultra settings average 188 FPS.

At 2560x1440, performance remains strong. Low settings average 202 FPS. Medium settings average 176 FPS, with a min of 150 FPS and a max of 202 FPS. High settings average 149 FPS. Ultra settings average 122 FPS.

At 3840x2160, the resolution stresses the GPU. Low settings average 109 FPS. Medium settings average 95 FPS, with a min of 81 FPS and a max of 110 FPS. High settings average 81 FPS. Ultra settings average 66 FPS.

CPU Role

The AMD Ryzen 7 3700X, a Zen 2 (Matisse) processor with 8 cores and 16 threads, operates at a base clock of 3.60 GHz and a boost clock of 4.40 GHz. Its 32 MB of L3 cache and 64 KB of L1 cache per core provide adequate memory hierarchy for gaming. The CPU’s average benchmark score of 34260 places it in the 84th percentile of all CPUs, and it is within 0.2% of the Intel Core i5-13450HX and 0.5% of the Intel Core Ultra 7 165H.

In Doom, the CPU’s role is most apparent at 1080p with lower settings. The 1080p Low average of 278 FPS is the highest recorded, but the gap to 1080p Medium (265 FPS) is only 13 FPS. This narrow margin suggests that the CPU is struggling to keep up with the GPU’s frame output. At 1080p Ultra, the CPU load is less severe because the GPU is more heavily taxed, resulting in 188 FPS—a figure that is 90 FPS lower than Low. The 1440p results show a more balanced distribution: the CPU can feed the GPU at 202 FPS on Low, but the GPU still dominates at 122 FPS on Ultra. At 4K, the CPU is never the bottleneck; the GPU is always the limiting factor, as even the highest 4K average (109 FPS on Low) is far below the CPU’s theoretical ceiling.

The 8-core, 16-thread configuration is well-suited for Doom’s multi-threaded Vulkan engine, but the Zen 2 architecture’s single-thread performance (Geekbench single-core score of 1593, Cinebench R15 single-core of 204) is the limiting factor at extreme frame rates. A processor with higher IPC, such as the Intel Core i5-13450HX, would likely improve the 1080p Low and Medium results, potentially pushing the average past 300 FPS. The 84th percentile ranking confirms the CPU is strong, but the data shows it is the weaker link in this pairing at sub-4K resolutions.
